Today is the 200th anniversary of the Primero Grito de Independencia -- the first shout of independence. In 1811, rebellions started in San Salvador against Spanish rule in Central America. From Wikipedia:
On November 5, the revolt began in San Salvador. According to tradition, the rebels waited for a signal from the bell tower of the Church of La Merced, but this did not occur on the scheduled time. The rebels later assembled on the town square outside the church where Manuel José Arce proclaimed in front of the public: "There is no King, nor Intendant, nor Captain General. We only must obey our alcaldes," meaning that since Ferdinand VII had been deposed, all other officials appointed by him no longer legitimately held power. A tumult in the square grew to the point that the intendant, Antonio Gutierrez y Ulloa, asked that the gathered name somebody to formally receive their demands. Manuel José Arce himself was chosen and selected as the leader by the crowd. Despite this, the insurrectionists took arms and proclaimed the total independence of San Salvador from the Spanish crown, but were later subdued.The rebellions which started in 1811 would be erupt for the next ten years until the final independence of the Central American countries from Spain on September 5, 1821.
